When pedofilic crossguards kick school childrens butts, they get booty particles stuck on their shoes. When the police/Chris Hansen track down pedos, they check the shoes for a bum sole. Because of this, you can see pedos lick their feet because it is a habit for them to lick the bum sole off of shoes.
Crossguard 1: How much more bum sole is on my shoes?
Crossguard 2: Depends on how many children you molested.
Chris Hansen: Why don’t you take a seat right over there?
